TEMPORARY IIUiaVEXTEivsIoN 1 Application meri Augusti, 19,27. serial No'. 210,600.

In lshipping automobiles, it is customary to support the same by the hubs of the wheels thereof in an elevated position within the freight car, or to tie the saine down by the hubs of the wheels thereofupon theyfloor of the freight car. Very often, the hubs of the automobile wheels are made so short that they will not engage or rest properly on the supports or decking and may noti be properly engaged by the tie-'down or holddown devices. It hastherefore been found necessary to provide temporary liub exten# sions for the vehicle wheels to properly engage the automobile supports or to be properly engaged by the tie-down devices, whereby lthe automobile will be eectively supported or held in position during shipment.

The primary object of the present invention, therefore, is to provide a simple and durable hub extension for use Lin the shipment of automobiles, having the advantagesl of being light in weight, capable .of being cheaply and easily manufactured, and so constructed as to effectively exclude the entrance of dirt and grit into the bearings of,

the wheel hubs when the dust Caps of the latter are replaced temporarily `by thepresent hub extensions.

Other objects will become stood, and the saine consistsin the novel form, combination and arrangement of parts hereinafter more fullydescribed, shown in 'f 35o Figure 3 movement within a freight car;

Figure 2 is an enlarged central longitudinal section of a hub extension constructed in accordance with the present invention, and

particularly adapted for use in connection with automobiles supported in an elevated position;

is a view similar toFigure 2, of

corresponding `parts la' modified forni` of the hub-extension shown i in the latter ligure;

yFigure llis a side elevational view showing the manner in which veach wheel of an automobile is blocked and tied down upon ythe floor of a-freightcar, the hub of the wheel being provided with a further modified form ofhub extension constructed in accordaiicewiththe present invention and particularly, adapted for engagement by a tie-down device;

fFigure isY an 'enlarged central longitudinal section of the hub extension shown in Figure4;'and i Figure 6 yis-a view similar to Figure 2, showing a'stil-l further slight modification of the device shownin the latter figure.V

Referring inore in detail to the drawings, 5 indicates the body of a freight car upon the fioory of which a number of the autoniobiles'are loaded as'at- 6. Other automobiles'las indicated at are supported in an elevationalposition within the freight car bodyduring shipment, as bythe use of suitablesiipports vor decking bucks 8, the elevated automobiles being supported by the hubs of the wheels thereofwhich engage or e v Vsuitably rest upon the bucks 8 as shown. v apparent asl the nature of the invention is bettery under- In cases where the hubs of the automobile wheels are excessively 'short so that they will not properly engage or rest upon the load-` ing bucks 18, extensions must be provided upon .said fhiib's. -For this purpose I pro'- -vide` lan extensionin the form of a .cylin- 'drical vbody 9` consisting ofa short rigid f I metal tube internally threaded at one end as aty lOV for being 'readily threaded onto the externally threaded end of the wheel hub indicated at lltby dotted lines. :The other end of the body oi" tube section 9 is preferably provided with a pair ofopposed openings l2'which-areffadapted to receive a bar or the lugs of a Spanner Wrench, whereby the hub extensinl may be readily threaded onto'the wheel hub. Secured in the outer plug consisting offa disk 13 having a marginal annular flange 14 firmly pressed out- ,w'ardlyinto: engagement .with the inner sura vso Wheel hub for causing undesirable excessive Wearv of the bearing parts when .the automo-v f.

bile is'later placedinto use. The deviceof Figure 3'is the' sameas tha of Figure 2, except that the-closureplug consists of a smaller metal disk 13a having a resilient return bent' annular'r` marginal flangey 14a Whose concentricl Walls are spaced, the outer Wall being irinly` pressed into engage-ment With the inner surface -of the Vbody 9. The resilient flange 14a insuresadditional tension so that the outer Wall of the flange will be tightly held against the body 9..

As shown in Figure (i, the flange 14 may be positively secured to, as Well as frictionally engaged With, the body9, by spotvvelding, riveting,V or the like, as atl, thus positively guarding against the possibility lieved that the construction and manner of use, as Well as the advantages of the present invention Will be readily understood and appreciated by those skilled in the art.

Minor changes may be made Without departing from the spirit and scope of the invention as Vclaime What I claim as new is A temporary Wheel-hub extension for use inthe shipmentV of` automobiles comprising a.short.;se.ction of rigid metal'tubing inter-V nallyvthreaded at one en'd for detachablel engagement with the threaded end of a' Wheel hub, and a closure plug fitted and secured in the other end of said tubing section,fsaid closure .plug embodying a sheet metal diskV having an annular marginal flange firmly pressed,outwardlyY against the inner surface of the tubingfsection, said tub- Y ing section havingspaced pairs of longitudinal slits insaid other end'thereof defining a tongue between 4the slits of each pair, said tongues being out-turned to form stops.
